Command Running Channel: Three kinds of channels: 1. Operational panel 2. Control terminal, 3. Serial communication port, choose 1 and 2 for master drive and 3 for auxiliaries

Built-in PID: Advanced PID arithmetic to realize closed loop control system

Stall Speed Control: Automatically limit current and voltage at running period to prevent tripping due to frequent overcurrent or overvoltage

Master and Auxiliaries connection: Extensible RS485 design, one drive in the system can be master and controls the other auxiliary drives (4 at most) to work by communication mode, Master drive sends PID feedback information to the auxiliary drives and monitors status of auxiliaries in real time. Any failure of the auxiliary drives does not affect the others

Water Shortage Protection: If the drive detects the pipe pressure is lower than the water shortage pressure set value, the system stops working automatically. After set period time, it restarts automatically for specified times. If pressure restores to normal, system works normally, otherwise, system stops automatically in case of idle running of pump and prolongs pump lifetime to the maximum extent

High Pressure Alarm: When pressure exceeds set pressure, it stops running automatically to avoid damage on pipe network due to high pressure

Automatic Energy-saving Running: Automatically lower output voltage under light loading to save energy

Password Setting: 4-bit password can be set with non-zero numbers, Exit password setting interface and the password will be valide in 1 minute

Parameters Locking: Define whether the parameter is locked in running or stopped status in case of misoperation
